The invention discloses a double-gear double-output integrated electric drive axle speed reduction transmission device which comprises a motor output shaft, the motor output shaft is connected with a gear shaft through a first-stage duplicate gear set spline, and the gear shaft is connected with an input shaft through a second-stage duplicate gear set spline. A low-gear gear set and a high-gear gear set are arranged on the outer side wall of the input shaft. According to the gear-shifting speed reducer, the structural design of the gear-shifting speed reducer is achieved through engagement of the spline housing, the problem that a traditional single-gear new energy light truck can maintain efficient area work only under few working conditions is solved, it is guaranteed that a motor can continuously work in the efficient area under various working conditions, and the working efficiency of the motor is improved. The speed reducer and the motor are coaxially designed, a duplex gear mechanism is selected, the radial size is greatly reduced, the radial size is shortened by 30% compared with an electric drive axle product of the same grade, the design is more compact, the speed reducer is more compact in size and more convenient to install, the efficient working area of the motor is wider, the power performance of a vehicle is better, and the endurance mileage of the vehicle is increased.

    本发明公开了一种双档位双输出集成电驱桥减速传动装置,包括电机输出轴,所述电机输出轴通过第一级双联齿轮组花键连接有齿轮轴,所述齿轮轴通过第二级双联齿轮组花键连接有输入轴,所述输入轴的外侧壁设有低速档齿轮组和高速档齿轮组。本发明通过花键套啮合实现换挡的减速器结构设计,解决了传统单档新能源轻卡只能在少数工况下才能维持高效区工作的问题,保证了电机在各种工况下都能持续在高效区工作,增加电机工作效率。减速器与电机同轴式设计,选用双联齿机构,径向尺寸极大缩减,与同级别电驱桥产品径向尺寸缩短30%,设计更加紧凑,减速器体积更加紧凑更方便安装,电机高效工作区更广,车辆动力性能更好,车辆续航里程增加。
